There’s a lot of buzz right now about honey bees—their health and their future.
The good news, where honey bees are concerned, is that there is good news. Just last month, the results of the annual winter bee loss survey were released, and losses of managed honey bee colonies from all causes were 23.2 percent for the past winter—a significant drop from the 30.5 percent loss reported for the winter of 2012-13.
But the really good news is that when it comes to pollination, honey bees aren’t the only game in town. Read more »
This week, USDA and its partners released the results of the eight annual national survey of honey bee losses. The survey shows good news—fewer honey bee colonies were lost this winter than in previous years. According to survey results, total losses of managed honey bee colonies from all causes were 23.2 percent nationwide.
That figure is a significant improvement over the 30.5 percent loss reported last winter, but it is still higher than the eight-year average loss of 29.6 percent and still far above the 18.9 percent level of loss that beekeepers say is acceptable for their economic sustainability.
While we’re pleased to see improvement this year, these losses are still too high. Read more »
The black dot on this honey bee is a varroa mite--a parasite that sucks vital fluids like a tick, although it also acts like a mosquito transmitting viruses and other pathogens to the bee.

You’ve probably heard that the honey bees in this country are in trouble, with about one-third of our managed colonies dying off every winter. Later this week, we will learn how the honey bees survived this winter. With severe weather in a number of areas in the U.S. this winter, a number of us concerned about bees will be closely watching the results.
While scientists continue work to identify all the factors that have lead to honey bee losses, it is clear that there are biological and environmental stresses that have created a complex challenge that will take a complex, multi-faceted approach to solve. Parasites, diseases, pesticides, narrow genetic diversity in honey bee colonies, and less access to diverse forage all play a role in colony declines. To confront this diverse mix of challenges, we require a mix of solutions – the odds are that we won’t find one magic fix to help our honey bees. Read more »
Work at USDA’s National Science Laboratories helps researchers and beekeepers better understand the effects of pesticide residue exposure on honey bees.

In agriculture, buzzing can be music to our ears—especially if that buzz means pollinators are busy helping produce our fruits, nuts, vegetables and field crops. Unfortunately, the sound of my favorite pollinator, the honey bee, has grown fainter in recent years due to higher rates of over-winter colony loss. These losses were initially attributed to a condition described as Colony Collapse Disorder (CCD).
Many factors involved with CCD are not yet fully understood. Honey bee research is focused on gathering data from multiple angles to increase the understanding of overall honey bee health. Many USDA agencies and industry partners are conducting research to better understand the complexities of honey bee health and working to develop best practices to improve the honey bee population.

You’re invited to the USDA Harvest Festival on Friday, November 22 from 10 a.m. to 2 p.m. Come celebrate the end of the growing season in the People’s Garden and at the USDA Farmers Market. Take advantage of the last opportunity of the year to shop the outdoor USDA Farmers Market located along 12th Street, SW in between Jefferson Drive and Independence Avenue in Washington, DC.
The day will be filled with fun activities and educational demonstrations that are free and fun for the whole family. Here’s a list of the planned events: Read more »
Last week’s cover of TIME magazine featured a story about the rapid rate of decline of honeybee populations across the globe. The article focuses on the question of the price we’ll pay if we don’t figure out what is killing the honeybee. A daunting thought when you think about the fact that one-third of all food and beverages are made possible through pollination and pollinators are valued at $15 billion annually.
This morning, Jim Jones from the Environmental Protection Agency (EPA), author Hannah Nordhaus and I joined TIME journalist Bryan Walsh on Twitter to discuss the topic and what is being done and what needs to be done. If you happened to miss the Twitter chat, you can follow what was said by searching #TIMEbees. Read more »
